You should still get a matching Elm call result if you land on the right delay. Even if NPCs make you skip several calls, the search Elm function in RNG Reporter can still track your calls and land you on the correct adjacent when you hit OK after you fill in the list. If you're only looking in the list, chances are you won't see matching calls for the Latios RNG because you could land on your adjacent up to 10 calls further up the list with that many NPCs advancing your frames.
